Ascending Tracts of the Spinal Cord

"...the ascending track to the spinal cord carries sensory information from the body up towards the central nervous system they are grossly divided into tracts that carry conscious sensation and unconscious Sensation will start with a conscious sensation the first that we will cover is the anterolateral system which is made up mostly by the anterior and lateral spinothalamic tract but it also features the spinal reticular and spinal technical tracks the anterior spinal thalamic tract is responsible for crude touch and pressure sensation while the lateral spinothalamic tract is responsible for pain and temperature generally the ascending Pathways have three neurons in the path compared to only two neurons in the descending Pathways the first order neuron in the anterolateral system comes from The receptors in the periphery and signups is with the second order neuron that has its cell body in the also Horn of the gray matter note that the first order neuron can Ascend one to two levels before sign up Ting on to the second order new run the second or the neuron then deficits to the other side of the spinal cord and it is at this point that they form the separate tracts the anterior and lateral spinothalamic tract these second-order neurons will carry the information up the spinal cord to the thalamus where they synapse to the third order on really they are located on the ventral posterolateral nucleus of the thalamus and from there the fibers will travel to the somatosensory cortex of the postcentral gyrus passing through the internal capsule note that the third order neurons do not decussate they travel to the ipsilateral cortex we said that the anterolateral system is made up mostly by the spinothalamic tract but there are also two others the spine reticular which is involved in the automatic response to pain and the spine a technical track which is involved in orienting the head and eyes to stimuli the other system involved in conscious sensation is the dorsal column medial lemniscus pathway named due to the fibers traveling in the dorsal column of the spinal cord and passing through the medial lemniscus in the brainstem the dorsal column medial lemniscus pathway is responsible for transmitting sensations of fine touch to touch discrimination vibration and proprioception slightly we take this few seconds our valued loyal listener about the best health and fitness podcast shows from the Nez pod Studios join us as we give you the best of the best health and wellness updates you can rely on for the treatment of chronic health problems class..."
